SEAMING AND CALKING KNIFE.

Application filed February 28, 1911.

Specification of Letters Patent.

Patented Dec. 26, 1911.

Serial No. 611,485.

To all whom it may concern:

Be it known that I, ANDREW J. CoMrToN, a citizen of the United States, residing at Trenton, in the county of Mercer and State of New Jersey, have invented new and useful Improvements in seaming-and Calking Knives, of which the following is a specification.

This invention relates to knives and more particularly to combined seaming and call:- ing knives.

The object of the invention is the provision of a handy and convenient tool by which the seams of boats may be cleaned and properly calked, and further means whereby nails or tacks may be removed.

Further objects of the invention will appear as the following specific description is read in connection with the accompanying drawing which forms a part of this application and in which:

Figure 1 is an elevation of a knife shtfiiing the novel features of my invention. Fig. 2 is a section therethrough. Fig. 3 is an elevation of a modified form. Fig. 4 is a similar view of a further modification.

Referring more particularly to the drawing 1 represents a blade which has secured on either side thereof intermediate its ends rounded handle members by means of the rivets 3. At one end of the knife the blade is broadened as at 4 into a calking instrument and is sharpened as at 5. The opposite end of the blade has a laterally extending head 6 which is formed into V-shape with cutting edges 7 and 8 on opposite sides thereof. Immediately opposite the head 6 is a head 9 having formed therein a notch 10 which may be engaged with tacks, nails or the like to extract the same. The under edge 11 is sharpened so that it may be used in the manner of a drawing knife. Extending above the heads 6 and 9 in a line with the blade 1 is an anvil 12 which is formed for the purpose of receiving the blows of a hammer. The upper edges 13 and 14 are preferably sharpened as shown but may be left dull as is found advisable.

In the modification shown in Fig. 3, the

blade 15 is provided with a laterally eX-- notch 19 on its under side. Extending abovev the heads 16 and 18 in line with the blade 19 is an anvil 20 which has an inclined face 21 adapted to receive the blows of a hammer.

In the modification shown in Fig.4, the cutting head 22 is similar to that shown at 6 in Fig. 1 and the cutting head 23 is similar to that shown in Fig. 3 with the exception that the end edge thereof is sharpened as at 24. In this modification there is also shown a tack or nail notch 25 in the calking end of the blade. The ends of the heads 9 and 18 may be used as anvils to drive the pointed heads 6 and 16 into the seams and the anvils 12 and 21 are used to drive the tools along the seams.

Having thus described the invention, what is claimed is 1. A tool comprising a body, a calking blade formed at one end thereof, a seaming blade formed at the opposite end thereof, an anvil formed on the seaming end of the tool and a handle member secured to opposite sides of the body intermediate the blades.

2. A tool comprising a body, a calking blade formed at one end thereof, laterally extending heads formed at the opposite end thereof, one of said heads being sharpened,-

the opposite head having a notch therein, and an anvil carried by the body.

In testimony whereof I aflix my signature two witnesses.
